The reason for the error message when using the regular way to install gems seems to be
% dir /var/lib/gems/1.9.1 insgesamt 4 drwxr-x--- 2 root root 4096 Mai 29 22:35 cache/
it's simply not readable for users other than root, thus forcing people to use the root account to proceed.
The file installed inside cache is
-rw-r----- 1 hadmut hadmut 120320 Mai 29 22:35 rake-10.0.4.gem
again with a permissions problem, which would be readable for the user only who ran bundle.
Wrong umask?
